I WILL MARK BRAINLIEST!!!!!! A direct variation function includes the ordered pair (4, 5). If y varies directly with x, and y is
nignag [31]

Answer: x=5

Step-by-step explanation:

\frac{2}{14} =\frac{x}{35}

\frac{x}{35}=\frac{2}{14}

simplify

\frac{x}{35}=\frac{1}{7}

multiply 35 on both sides

\frac{35x}{35}=\frac{1\cdot \:35}{7}

\frac{1}{7}  \cdot 35=5

x=5

Find the area of a circle with diameter 18 yd.
larisa [96]

Answer:

  • Area of the circle is 254.34 yd²

Step-by-step explanation:

Given:

  • Diameter of circle = 18 yd
  • π = 3.14

To Find:

  • Area of circle.

Solution:

  • Diameter = 18 yd
  • Radius = 18/2 = 9 yd

We know that,

\: \: \:  \:  \dashrightarrow \:  \:  \:  \:  \: {\underline{\boxed{\sf{Area \:  of  \: circle = \pi r^2}}}} \\ \\

Substituting the required values,

\\

\: \: \:  \:  \dashrightarrow \:  \:  \:  \:  \: \sf Area_{(circle)} = 3.14 \times  {(9)}^{2}  \\ \\

\:  \:  \:  \:  \dashrightarrow \:  \:  \:  \:  \: \sf  Area_{(circle)} = 3.14 \times 81 \\  \\

\: \: \:  \:  \dashrightarrow { \:  \:  \:  \:  \: \sf Area_{(circle)} = 254.34 \:  {yd}^{2}}  \\  \\

<u>Hence,</u>

  • <u>Area of the circle is 254.34 yd²</u>

Please help, I have an algebra test tomorrow and i'm trying to understand problems like this.
Sonja [21]

Answer:

L=P/2-W

Step-by-step explanation:

P=2(L+w) - Solve for L

1) Use the distributive property on the right side of the equation:

P=2L+2w

2) Subtract both sides by 2w:

P-2w=2L

3) Divide both sides by 2 to Isolate L:

P/2-W=L
